摘要
采用大型有限元数值模拟软件ANSYS,对深部软岩巷道锚注支护前后围岩变形破坏规律进行了数值模拟,对锚注支护前后围岩的应力、位移及塑性区的变化情况等进行了系统分析,结果表明,锚注支护显著提高了围岩的强度和承载能力,有效地控制了深部软岩巷道的损伤变形。
By means of numerical simulation software ANSYS, deformation failure regularity of bolt-grouting support and bolt support for deep soft roadway is simulated. The stress, displacement and plastic zone of bolt-grouting support and bolt support for deep soft roadway is systematically analyzed. The research results indicate that the strength and bearing capacity of surrounding rock for bolt-grouting roadway is greatly increased. So the deformation of deep soft roadway is effectively controlled.
